Overview
MIC2544/2548 Micrel MIC2544/2548 Programmable Current Limit High-Side Switch Preliminary Information General Description The MIC2544 and MIC2548 are integrated high-side power switches optimized for low loss dc power switching and other power management applications, including Advanced Configuration and Power Interface (ACPI).
The MIC2544/48 is a cost-effective, highly integrated solution that requires few external components to satisfy USB and ACPI requirements.
Load current management features include a precision resistor-programmable output current-limit and a soft-start circuit which minimizes inrush current when the switch is enabled.
Thermal shutdown, along with current-limit, protects the switch and the attached device.
The MIC2544/48’s open-drain flag output is used to indicate current-limiting or thermal shutdown to a local controller.
The MIC2548 has an additional internal latch which turns the output off upon thermal shutdown providing robust fault control.
The enable si...
